Dataset : IQ Samples for V2X Communication System combined with Narrow-Band Interference

This paper explores the applications of the 45 MHz U-NII-4 band in vehicle-to-everything (V2X) communication system, a technology adopted (or being adopted) by numerous countries to facilitate safety warning applications and mitigate collision risks. However, the operational efficiency of V2X systems can be undermined by intentional and unintentional interference provoked by the increasing user base in adjacent bands and potential malicious entities in the V2X operating band. This study offers a comprehensive review of the possible interference sources, with a primary focus on in-band interference at road side infrastructure. A detailed analysis is conducted by evaluating the impact of varying interference power levels and frequency offsets on V2X packet reception. To address the interference detection, we introduce a time-frequency processing of the time domain data which is easily implementable by the chipset vendors, operates during standard receive cycles and provides PHY-layer metrics to the host layers.
